Ok I have checked the UA page and it says I have 1 bag free and will have to pay the 75 Euros for the second bag even if I am now flying business of the exit.
Now this may still not be the correct info since LH is the most significant carrier.
The ticket is a LH one but since LH doesn't fly to ANC they do that with UA (code share) I guess I will just have to wait and see what happens at the airport.
I promise to come back and tell you what really happend.
